ROTARY ENGINE.

To all whom it may concern Be it known that I, EDWARD B. GALE, a citizen of the United States, residing at Binghamton, in the county of Broome and State of New York, have invented certain new and useful Improvements in Rotary Engines, of which the following is a specication. v

My invention relates to an improvement in rotary engines.

The invention consists of a runner having sliding pistons, which pistons are caused to be moved by the engagement of a cam located Within the runner and the inner surface of the cylinder of the engine. When the pistons are engaged by the inner surface of the cylinder, they are forced inward toward the cam, and when engaged by -the cam, the pistons are forced outward toward the casing. Therefore the pistons are, at some stages during the revolution of the rotor or runner, on one side of the runner or the other, and then again a portion of the piston will be on one side of the runner and the remaining portion on the opposite side of the runner, and it is the object of this invention to provide means whereby the live steam will be conducted on both sides of the runner, so that the piston will always receive the pressure of the steam or other fluid on each side of the runner.

The invention consists in certain other novel features of construction and combinations of parts, which will be hereinafter fully described and pointed out in the claim.

In the accompanying drawings :.-Figure 1 is a view in side elevation with one of the sides of the heads of the cylinder removed, Fig. 2 is a sectional view on the line 1-1 of Fig. 1, Fig. 3 is a longitudinal vertical section, and Fig. t' is a detail view showing the manner of mounting the piston in the runner. Fig. 5 is a view in perspective of the piston and the bearings therefor.

A, represents the cylindrical casing of the engine; 1 represents the head to which the cylinder head or cam 2 is connected. The shaft 3 is journaled in the cylinder head or cam eccentrically, and mounted upon the shaft is a runner or rotor i, the runner being mounted in the cylinder eccentrically,.

and extending through the wall of the runner is a piston 5. An inlet port 6 is provided in the casing A for the admission of the live steam or other fluid for propelling the runner, which live steam is indicated by Specification of Letters Patent.

the arrows in full lines. Ports 7 and 8 are formed in the casing to which are connected conduits or pipes 9 leading to ports l0 and 11 formed in the wall of the cam or cylinder head 2. Ports 7 10, 8, and l1 with the pipes 9l form by-passes for conducting the live and exhaust steam from one side of the runner to the other for the purpose of equalizing the pressure upon the pistonV and relieving all pressure in front of thevpiston as it travels around the casing. As is indicated more clearly in Fig. 3, it will be noted thatthe live lsteam is received on both sides of the runner, and is engaging the piston 5, the -steam being conducted from the crescent shaped chamber` BV by the bypass to the opposite side of the runner into the crescent shaped chamber C, so that the steam is exerting its pressure against the piston on both sides of the runner. It might be stated that the casing is divided into two crescent shaped chambers bythe runner and cam, the crescent shaped chamber B being formed between the runner and the casing A, and the crescent shaped `chamber C is formed between the runner and the cam 2. v

As the piston is moving around the casing, it is naturally driving the exhaust steam which was the live steam used upon the previous rotation of the piston head with it, which exhaust steam is indicated by the arrows in dotted lines. rlhe exhaust steam is on both sides of the runner in the position shown in Fig. 3, at the point at which the piston is now located, and as the piston continues to move, the exhaust steam will pass from between the runner and casing through the port 8 into the conduit 9, and into the port 11 where it will be in the crescent shaped chamber C between the cam 2 and runner 4. The exhaust steam eventually is discharged through the ports 12 and 13 formed in the wall of the cam 2.

I have provided two openings or ports 12 and 13 for the exhaust steam to prevent any choking and causing the same to be conducted from the crescent shaped chamber C from every point and relieving` any possible compression or vacuum therein. It will be noted that the outlet ports 8 and 13, and the inlet port 10 are located at points adjacent to where the runner and casing or cam meet, thereby preventing any vacuum, and insuring the removal of all of the exhaust steam from one chamber to the other or discharging it entirely from the cylinder, and for the admission of the live steam at the point where it will immediately come in contact with the piston as soon as it is exposed on one or bot-h sides of the runner.

From the foregoing, it will be seen that provision is made for utilizing the steam that is admitted to the casing or cylinder throughout the entire rotation of the runner by providing luy-passes which allow the steam to be conducted from one side of the runner to the other and thereby exerting its pressure against the piston on one or both sides of the ruimer.

In the disclosure, I have only shown one piston, but, in some instances, I might find it to advantage to provide more than one, and other sliglit changes might be made in the form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I do not wish to be limited to the exact construction herein set forth, but

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is

in a rotary engine, the combination with a casing having inlet and outlet ports, of a runner eccentrically mounted therein, a piston slidably mounted in the runner, a cam mounted in the casing adapted to force the piston in one direction, and the casing adapted to force the piston in another direction,

said ruimer dividing the cylinder into two crescent shaped chambers, one of said chambers having the inlet port connected thereto, and the other, or inner chamber having the outlet port connected thereto, a by-pass in communication with the two chambers for conducting the live steam from the outer chamber to the inner chamber beyond the contacting point between the runner and cam so that the live steam will come in contact with the portion of the piston which extends into the inner chamber, and another by-pass in communication with the inner and outer chambers for conducting the eX- haust steam from the outer chamber to the inner chamber and located adjacent to the point where the runner and casing meet, so that the exhaust steam is conducted from the outer chamber through the pass to the inner chamber prior to the piston coming in contact with the casing, thereby relieving any pressure ahead of the piston and causing` the live steam to exert its pressure against the entire face of the piston during the entire revolution of the runner.

1n testimony whereof I afl/ix my signature in the presence oi two Witnesses.
